Product Overview
AR9382 is the single-chip, dual-band (2.4/5 GHz), 2-stream 11n solution with PCIe interface. It packs the breakthrough Signal-Sustain Technology (SST) technology that enhances rate-over-range performance. SST is a set of advanced technologies and features enabled by 802.11n including LDPC, TxBF and MLD.
The end result is an impressive increase in rate-over-range of ~+100% at short range, ~+50% at mid range and ~+25% at long range.
To reduce the manufacturing cost, the AR9382 has successfully integrated external components such as both the 2.4/5 GHz LNA and PA, switching regulators and EEPROMs. It has dramatically reduced the RBOM and has made the board manufacturing easy and simple.
Despite its mighty performance and high degree of integration, AR9382 consumes even less power in every operation mode – active TX, active RX, idle associated and sleep than the previous generation solution. It keeps the notebook and other computing platforms running much longer on a single battery-charge, while providing TCP throughput of more than 200 Mbps when used in 2x2 mode.

AR9382 is also optimized for Atheros Direct Connect™ P2P applications. With its Fast Channel Switch (FCS) feature, the channel switching time between the 2.4 GHz and 5 GHz bands is reduced from 10 ms to as little as 1 ms.
